The attack targeted FortiGate firewalls, which are widely used for network security, and highlights the potential impact on critical infrastructure.

The use of commercial generative AI services facilitated the breach, allowing the threat actor to quickly and easily compromise a large number of devices. As noted by The Hacker News, this incident demonstrates the increasing sophistication of threat actors and their ability to leverage AI for malicious purposes. The fact that the threat actor was able to use AI services to breach such a large number of devices in a short amount of time highlights the need for organizations to prioritize the security of their FortiGate devices and ensure that they are running the latest software updates.

The attack is believed to have exploited a combination of vulnerabilities, including CVE-2022-26187, which is a remote code execution vulnerability in the FortiGate firmware. This vulnerability allows an attacker to execute arbitrary code on the device, potentially allowing them to gain control of the device and access sensitive data. As reported by Fortinet, this vulnerability is considered critical and should be patched immediately.

In addition to patching vulnerabilities, organizations should also ensure that their FortiGate devices are properly configured to prevent attacks. This includes configuring the device to only allow incoming traffic on necessary ports and protocols, as well as implementing robust password policies and multi-factor authentication. As recommended by CISA, organizations should also implement a defense-in-depth strategy, which includes multiple layers of security controls to protect against cyber threats.

Technical Details

The technical details of the attack are still emerging, but it is believed that the threat actor used a combination of AI-powered tools to breach the FortiGate devices. These tools included machine learning algorithms and natural language processing, which allowed the attacker to automate their attacks and quickly compromise a large number of devices.

The attack is believed to have started with a reconnaissance phase, in which the threat actor used AI-powered tools to identify vulnerable FortiGate devices. This was followed by an exploitation phase, in which the attacker used the CVE-2022-26187 vulnerability to gain control of the device. Once the device was compromised, the attacker was able to access sensitive data and move laterally within the network.

The use of AI-powered tools allowed the threat actor to automate their attacks and quickly compromise a large number of devices. This made it difficult for organizations to detect and respond to the attack, as the attacker was able to move quickly and evade detection. As reported by The Hacker News, this incident highlights the need for organizations to invest in AI-powered security tools to stay ahead of sophisticated threat actors.
